Orochimaru's excited at the thought of finally acquiring Sasuke's body and with it the Sharingan, he begins thinking of his journey of trying to acquire the Sharingan, from his failed attempt at Itachi, to everything he's done to acquire Sasuke. He notes that Sasuke is truly a genius, and nobody but him could have understood his thirst for power, and nobody could have trained Sasuke better than him. He notes that with enough time, Sasuke might even surpass Itachi.
Orochimaru then notices that there is someone outside his door, and commands him to show him self. Suddenly a lightning based chakra pierces through the door and head's towards Orochimaru. He blocks the technique with his forearms. The door is slashed and Sasuke enters.
